- The spring constant is the restoring force of a spring per unit of length. Within the elastic limit of any material, there is a linear relationship between the displacement of a particle and the force attempting to restore the particle to its equilibrium position.

Gravitational Force From the equation, it is clear that gravitational force is affected by the masses of the bodies and the distance between these bodies. The product of the masses is directly proportional and the square of the distance is inversely proportional to the force of attraction.

Gravitational constant According to the law of universal gravitation, the attractive force (F) between two bodies is directly proportional to the product of their masses (m 1 and m 2), and inversely proportional to the square of the distance, r, (inverse-square law) between them:

NEWTON'S  UNIVERSAL LAW OF GRAVITY If, for example, we triple the distance between two objects, the gravitational force between them drops, not by three times, but by three times three times, or nine times. Newton summarized the relationship between the strength of gravitation pull and these three factors in this equation: Fg = G M1 M2 / (D12)2. where M1 and M2 are the masses of the objects, and D12 is the distance between the centers of the two objects.

Gravitational field & Gravitational field strength The gravitational field strength (g) at any point in a gravitational field is the gravitational force per unit mass exerted on any body placed at that point. 1  SI unit of gravitational field strength is newton per kilogram.ravitational field & Gravitational field strength. Any two bodies in the universe attract each other with a force. This spectacle is called the gravitational attraction. This force of attraction is known as the gravitational force or force due to gravity.

Why do people indulge in emotional eating? People indulge in emotional eating to feel better. When we are stressed, lonely, or even bored we may experience a drop is some of our body’s chemical neurotransmitters and hormones. This drop may set off triggers in the brain that cause us to eat to take away that bad or uneasy feeling we are having.

How to Calculate a Spring Constant Using Hookeâs Law (k is called the spring constant, which measures how stiff and strong the spring is. x is the distance the spring is stretched or compressed away from its equilibrium or rest position.). The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium.

Homework 1 SOLUTION:The gravitational force is always attractive, and the magnitude of the force is: Gm1m2/r2. The electric force is attractive if the charges have opposite signs, and is repulsive if the charges have the same sign. The force magnitude is: kq1q2/r2. The gravitational and electric force are very similar in each having the inverse distance- squared rule, and in having the magnitudes depending in a linear and symmetric fashion on properties of the two objects.

- For objects a long way from the Earth s surface, we must use a more general definition: The gravitational potential energy of an object is the work done in moving the object from a very large distance away to a point in the gravitational field of the Earth.he mass of an object is a measure of the amount of matter contained in the object. Mass is a scalar quantity. The weight of an object is the force due to a gravitational field acting on the object. Weight is a vector quantity.

Understanding the Surface Gravity of Planets Fg= GM1M2/R. This shows that the gravitational force between two masses is found by product of their masses, times the gravitational constant – G, and divided by the square of distance between them. The value of G was originally determined experimentally by Henry Cavendish and has a value of 6.67x10 N (m/kg-s)

Gravitational field The gravitational field equation is. where F is the gravitational force, m is the mass of the test particle, R is the position of the test particle, is a unit vector in the direction of R, t is time, G is the gravitational constant, and ∇ is the del operator. gravitational field can be defined using Newton's law of universal gravitation. Determined in this way, the gravitational field g around a single particle of mass M is a vector field consisting at every point of a vector pointing directly towards the particle.
